場景：測試HAproxy服務的TCP代理服務，與nginx的TCP代理做性能對比
部署過程：
1、下載haproxy-1.8.0.zip，下載頁面https://github.com/haproxy/haproxy/tree/v1.8.0
2、安裝部署haproxy
unzip haproxy-1.8.0.zip
cd haproxy-1.8.0
make TARGET=linux26 ARCH=X86_64 PREFIX=/home/homework/haproxy
make install PREFIX=/home/homework/haproxy
cd /home/homework/haproxy
mkdir etc logs
cd etc
vim haproxy.cfg
----------配置文件---------------

chown homework.homework -R /home/homework/haproxy/
3、開啓日誌接收
vim /etc/rsyslog.conf
下面兩行註釋去掉
$ModLoad imudp
$UDPServerRun 514
添加配置
local3.* /home/homework/haproxy/logs/access.log
vim /etc/sysconfig/rsyslog
SYSLOGD_OPTIONS="-c 5"修改爲下面配置
SYSLOGD_OPTIONS="-r -m 0 -c 2"
/etc/init.d/rsyslog restart
4、啓動haproxy
/home/homework/haproxy/sbin/haproxy -f /home/homework/haproxy/etc/haproxy.cfg
5、檢查haproxy日誌是否有輸出
tail /home/homework/haproxy/logs/access.log
Dec 4 10:38:50 localhost haproxy[96612]: Proxy stats started.
Dec 4 10:38:50 localhost haproxy[96612]: Proxy stats started.
至此服務部署完成、重啓服務的腳本自行創建，這裏就不貼出來了。
